Overview
Colonia Hidalgo wastewater treatment plant in Durango, Mexico, serves 1,460 people with secondary treatment. It discharges 172.80 m³/day and has a designed capacity of 259.20 m³/day.
Colonia Hidalgo is a wastewater treatment plant located in the municipality of Durango, in the state of Durango, Mexico. It serves a population of approximately 1,460 residents, making it a small-scale facility focused on local community wastewater management. The plant is situated in an inland area, far from coastal zones, and operates under Mexico's national water regulations. The plant provides secondary treatment, which is the standard biological process for reducing organic matter and suspended solids. With a designed capacity of 259.20 m³/day and an actual discharge volume of 172.80 m³/day, the facility operates below its full capacity, indicating room for future growth or seasonal variations. As a small plant, it falls under Mexico's regulatory framework for municipal wastewater, which requires compliance with official standards (NOM-001-SEMARNAT) for discharge quality. The treated effluent is discharged into local water bodies that eventually drain into the Pacific Ocean via the Nazas River basin, a critical water source for the arid region of Durango. The plant plays a vital role in protecting downstream ecosystems and supporting water reuse for agricultural or environmental purposes in this water-scarce area.
Environmental context
The plant discharges into the Nazas River basin, which flows through the semi-arid landscape of Durango and ultimately reaches the Pacific Ocean via the Laguna de Mayran and the Rio Grande de Santiago system. This watershed supports diverse aquatic life and is an important water source for local agriculture. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding downstream water quality in a region where water resources are limited.
